When i port my old demo application from platform 6.0 to 7.0, fatal crash comes across. It looks like is relative to linker with platform so library, but crash back trace seems problem comes from Activity starting process. Does some body has any ideal about this condition? Back trace is:

Demo Activity is simple:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRootView = (ViewGroup) findViewById(R.id.rootView);
Logger.LOGI("Before new VrSurfaceView");
mSurfaceView = new CustomSurfaceView(MainActivity.this);
Logger.LOGI("After new VrSurfaceView");
LayoutParams lParams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
mRootView.addView(mSurfaceView, lParams);
mSurfaceView.getHolder().addCallback(new Callback() {
@Override
public void surfaceDestroyed(SurfaceHolder holder) {
Logger.LOGI("surfaceDestroyed");
}
@Override
public void surfaceCreated(SurfaceHolder holder) {
Logger.LOGI("surfaceCreated");
}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
Logger.LOGI("surfaceChanged");
}
});
Logger.LOGI("onCreate finished(before sleep): " + mSurfaceView.getAppPtr());
try {
Thread.sleep(4 * 1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
Logger.LOGI("onCreate finished(after sleep): " + mSurfaceView.getAppPtr());
}
@Override
protected void onStart() {
super.onStart();
Logger.LOGI("onStart");
}
sleep operation in onCreate is used to check if crash happens in other thread, and result is after 4 seconds(onCreate called), application crashed as before. onStart is never be called. CustomSurfaceView's parent VrSurfaceView will load the libsdk.so located at /system/vendor/lib/ directory.
/**

static {

}
}
I also checked the libsdk.so used only Android Published NDK APIs, so it may not because of usage of platform so library. It is so confused...
